The church I had to go to wasn't a mega church but it was a modern style one. Apparently alot of affluent people went because the pastor always said they weren't giving enough money. They made us sign pledge cards and tried to get our bank accts. I wouldn't give them mine but my mom did. We had to sing songs too saying that since jesus gave alot to us we had to give back now - so we would feel guilty. They even sent letters telling us how to budget our money to make sure the church got their cut. I always thought god sure needs alot of money" lol.
